Our impact calculations are based on rigorous data sourcing, analysis of the actions recorded by our users, and inputs by our users.

To ensure data integrity, we employ a mix of verification levels:

The Meatless Meals initiative has shown significant engagement and impact, directly avoided up to 14.9 tons of CO2e emissions. The annualized impact projection of 151.4 tons is calculated by assuming that each user maintains the habit of one meatless day per week for a year. This conservative estimate suggests a substantial potential for long-term emissions reduction through dietary changes. The high number of actions relative to unique users indicates that many participants are incorporating meatless meals into their regular routines, suggesting successful behavior change and habit formation.

Choosing meatless meals offers substantial benefits beyond reducing carbon emissions. At scale, adopting a plant-based diet offers health, environmental, and economic benefits.

The Alternate Transportation action has demonstrated impressive results in reducing carbon emissions. We've achieved a direct CO2e avoidance of up to 41.1 tons. The annualized impact projection of 464.5 tons is based on the assumption that each user maintains this habit once per week for a year. This significant figure highlights the potential for substantial emissions reduction through changes in transportation choices.

At scale, choosing public transport, biking, or walking over driving provides economic, environmental, and health advantages while fostering community well-being.

Compost is our original habit action, and even as many additional actions have been introduced to the app, it has continued to show consistent engagement and impact. We've directly avoided up to 5.7 tons of CO2e emissions. The annualized impact projection of 293.3 tons is calculated differently depending on user inputs: for users who indicate that they were already composting, we assume sustained daily composting, whereas for new adopters, we only include those who have logged at least 6 composting actions in the app. This method ensures a conservative and realistic estimate of long-term impact. The high number of actions per user (averaging over 7 per user) indicates strong habit formation and consistent engagement with composting practices.

Beyond avoiding methane emissions, composting food scraps improves soil health, reduces landfill waste, and supports environmental sustainability while offering economic and community benefits when implemented at scale.

Energy efficiency is an important contributor to CO2e reduction, with users participating in habits like turning off unnecessary lights and signing up for Ohm Connect. These actions have directly reduced up to 3 tons of CO2e emissions, with an annualized impact projection of 105.1 tons. For the "lights out" habit, we assume all users who log the action will continue this behavior nearly daily, as the habit is designed primarily to teach app mechanics for a practice many users already follow. For Ohm Connect, we base the projection on actual conversion rates to Ohm accounts, calculating only for users who have successfully converted. This dual-method approach ensures a realistic and data-driven estimate of sustained impact.

Reducing energy use through programs like OhmConnect or simple actions like turning off lights offers financial, environmental, and community advantages alongside emissions reductions.

While our water conservation actions (installing low-flow gear, turning off the tap while brushing teeth, and keeping showers less than five minutes) primarily contribute to our water impact, they do contribute to CO2e reduction. These actions reduce emissions by lowering energy use for water heating and distribution. Together, they have directly reduced up to 4 tons of CO2e emissions, with an annualized impact projection of 72.7 tons.

For the tooth-brushing habit, we assume users who log the action will continue it nearly every day, similar to the "lights out" habit. For low-flow gear installations, only verified actions are included in the impact calculations. For five-minute showers, we conservatively estimate that users who adopt the habit maintain it twice per week throughout the year. This balanced methodology ensures a realistic assessment of long-term impact while capturing the significant potential of water-saving behaviors to reduce emissions.

Adopting water-saving habits not only reduces emissions, but also provides financial, environmental, and societal benefits when adopted at scale.
